Embodiment 1

[0019] 1) Process the semi-coke through a crusher and a screening machine to obtain coal particles with a particle size of ≤50mm;

[0020] 2) Process the PCI coal through a crusher and a screening machine to obtain a coal particle size ≤ 50mm;

[0021] 3) Inject semi-coke and PCI coal into the hopper at a mass ratio of 50:50, and the hopper is divided into two parts by a partition, one part is used for injecting semi-coke, and the other part is used for injecting PCI;

[0022] 4) Mix the semi-coke and PCI coal in the hopper into the vibrating hopper below the hopper to obtain mixed pulverized coal;

[0023] 5) Put the mixed coal powder mixed in step 4 into the gasifier at 1100°C for reaction to generate syngas for indirect coal liquefaction.

[0024] The hydrogen-to-carbon ratio of the syngas is controlled at H 2 / CO>1.7. The comparison of the obtained coal synthesis gas with the synthesis gas obtained using PCI is shown in Table 1.

Abstract

The invention aims to provide a semi-coke mixed burning method. The method is mainly used to provide synthetic gas for coal indirect liquefaction. The method comprises the following steps: mixing semi-coke with blast-injection coal in proportion, processing through a crusher and a screener to obtain appropriate coal granules, adding the coal granules to a vaporizing furnace at 1100DEG C, and reacting to generate the synthetic gas for coal indirect liquefaction. The method greatly reduces the requirements of coal indirect liquefaction on the kind of coal, improves the applicability and economy of a coal indirect liquefaction technology, further develops the industrial application of semi-coke, and improves the industrialization level.

Description

technical field [0001] The invention belongs to the field of coal chemical industry, and in particular relates to a semi-coke mixed burning method, which is a process for providing synthesis gas for coal indirect liquefaction through mixed burning semi-coke. Background technique [0002] Indirect coal liquefaction is to gasify and purify coal to produce H 2 Raw material gas whose / CO ratio meets the requirements of synthetic oil, and then synthesize the required liquid product under certain pressure, temperature and catalyst conditions. Since my country's overall energy characteristics are "rich in coal, less oil, and gas", from the strategic point of view of my country's energy security, starting from the diversification of energy sources, and according to the characteristics of my country's energy reserves, the use of coal-to-oil technology can help my country has got rid of excessive dependence on imported crude oil and petroleum products and improved national energy secu...
